WARNING LABEL

86401410 Operators Manual - Cadet 115V

Safety

Electrical:

In the USA, this machine operates on a standard 15

amp 115V, 60 Hz, A.C. power circuit. The amp, hertz,

and voltage are listed on the data label found on each

machine. Using voltages above or below those

indicated on the data label will cause serious damage

to the motors.

Extension Cords:

If an extension cord is used, the wire size must be at

least one size larger than the power cord on the

machine, and must be limited to 50 feet (15.5m) in

length.

Grounding Instructions:

This appliance must be grounded. If it should malfunc-

tion or break down, grounding provides a path of least

resistance for electric current to reduce the risk of

electric shock. This appliance is equipped with a cord

having an equipment-grounding conductor and

grounding plug. The plug must be inserted into an

appropriate outlet that is properly installed and

grounded in accordance with all local codes and

ordinances.

This appliance is for use on a nominal 120-volt circuit,

and has a grounded plug that looks like the plug in "Fig.

A". A temporary adaptor that looks like the adaptor in

"Fig. C" may be used to connect this plug to a 2-pole

receptacle as shown in "Fig. B", if a properly grounded

outlet is not available. The temporary adaptor should

be used only until a properly grounded outlet (Fig. A)

can be installed by a qualified electrician. The green

colored rigid ear, lug, or wire extending from the

adaptor must be connected to a permanent ground

such as a properly grounded outlet box cover.

Whenever the adaptor is used, it must be held in place

by a metal screw.

Improper connection of the equipment-grounding

conductor can result in a risk of electric shock. Check

with a qualified electrician or service person if you are

in doubt as to whether the outlet is properly grounded.

Do not modify the plug provided with the appliance - if it

will not fit the outlet; have a proper outlet installed by a

qualified electrician.

Le raccordement incorrect du conducteur de terre

d'équipement peut entraîner des risques d'électrocu-

tion. Vérifiez auprès d'un électricien qualifié ou d'un

responsable de l'entretien si vous avez quelque doute

que ce soit quant au raccordement à la terre de votre

prise murale. Ne modifiez pas la fiche fournie avec

l'appareil : si elle ne correspond pas à la prise murale,

faites installer une prise adéquate par un électricien

qualifié. Utilisez-le uniquement sur des réceptacles

protégés GFCI.

NOTE: Be sure dome is seated on recovery tank, and

float shut-off is installed correctly.

2. Adjust brush to proper setting.

NOTE: For good operation the brush must skim the

carpet. If circuit breaker trips, raise brush to prevent

damage to motor or carpet.

3. Turn on pump and vacuum motor switches

The intermittent setting requires the operator to

hold the switch in the "on" position with the thumb,

and is typically used in small areas where short

cleaning passes are made.

The continuous setting allows the operator to set

the switch in the "on" position with one touch, and

is typically used in large areas where long cleaning

passes are made.

Cleaning Procedure

1. Start at wall closest to power outlet. Pull straight

back without pushing down on handle.
